Abstract (en)
The sealing assembly comprises a bore (25) in a housing (20), a plurality of seal rings (31, 32, 33) and a shaft (10). The bore (25) comprises a plurality of seats (21, 22, 23) disposed at different seat radius for the seal rings. The bore comprises for each pair of adjacent seats axially inward of an inner end of the outward seat and proximate to the inward seat a chamfer (221, 231) extending radially inwardly over an inward axial distance. The chamfer between each pair of seats allows for the radial contraction of the seal rings (31, 32, 33) upon assembly.
